说明：  共轭梯度算法，非常经典，大家相互交流，如果大家有更好的资源也上传啊，非常感谢(Conjugate gradient algorithm, very classic, everyone to communicate,)

说明：  10种比较经典的数字滤波C程序，比较有用(Comparison of 10 C classical digital filtering procedures, more useful)

Harris角点检测，附有图片，对进行电子稳像技术研究可以提供一定的帮助。(Harris corner detection, with a picture of the electronic image stabilization technology can provide some help.)

matlab里FFT变换时的频移程序，自动将FFT变化后的数据移到零频两边，方便好用(FFT transform in matlab frequency shift when the process changes automatically after the FFT to the zero-frequency data on both sides, easy-to-use)

说明：  《ofdm关键技术与应用》（汪裕民）一书中第10章有详细说明，在MATLAB上跑过，没有问题(&quot Ofdm technology and application&quot (Wang Yumin) Chapter 10 of the book are detailed in MATLAB, Running, no problem)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )
